Job argumnet creation is now actually legible AND works with the new style of inputs/outputs as well as job definition files.

Standardized and cleaned up test folder.  All files no loaded from base locations.  Each test class has a __name__ == __main__ to run just the individual test case.

Heavily updated workflow_job parsing & validation.  Addeded several tests to confirm the validity of new parsing.  additional_inputs no longer exist, and input / output files are defined as dicts instead of lists.  References refer directly to the dict key names instead of a list index.
